I'm attempting to figure out the least wrong way to go about adding
custom configuration to the /kernel/drv/sd.conf file on a SmartOS
system. I'm not seeing an obvious way. Why I'm attempting to do this
follows.
I've been handed hardware to prototype an SDC deploy upon. I've spent
most of a day attempting to figure out how to get SmartOS to start.
I'm using Dell R820 servers, with the PERC H310 raid controller with
all the drives set to pass through.
Attempting to install SDC or SmartOS results in the symptoms of
multiple messages of "WARNING: Device <path> failed to power up", and
creation of the zones pool to fail, with the installer bombing out in
a weird spot, with little help to tell me what had happened.
Researching that error message lead me to the thread at
http://marc.info/?l=zfs-discuss&m=133715468013989&w=2 which gave me
enough to figure out that if I add the following configuration to
/kernel/drv/sd.conf, and reload the sd driver, I get a functional system.
sd-config-list= "SEAGATE ST9146853SS", "power-condition:false",
<existing entries>;
This configuration line is sadly not generic and specifies the model
of drives I have to work with.
Now obviously, I can't really do this kernel configuration change as a
service, because all of those would be on the zones pool, on the disks
that won't work before this configuration is applied.
I'm not particularly familiar with what parameters I can pass at boot
time to the Illumos kernel. Taking the Joyent official images and
doing a repeatable small alteration to the boot parameters seems like
a reasonable path. I don't know if it's possible, or how.
The other option I can come up with is doing a custom build of
SmartOS, and eventually SDC to incorporate the parameters I need.
Are there any other options?
Thank you.
